MOUNTING Fen Fuses.

Specification of Letters Patent.

' Patented Feb. 2, 19.09.

To all whom it may concern:

Be it known that I, J OHN J. LYNG, citize of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Mountings for Fuses, of which the following is a full, clear, concise, and exact description.

My invention relates to a mounting for fuses, and its object is-to provide a mounting which will be cheaper and easier to manufacture than the ordinary types now in use, while equally eflicient and satisfactory in operation and less liable to accidental I will describe my invention particularly by reference to the accompanying drawing,

in which Figure 1 is a view of the fuse mounting, partially in section, and the fuse held there- 11); Fig. 2 is a detail view of the tube of refractory insulating material, which forms the body of the device; and Fig. 8 is an end view.

The same letters of reference indicate the same parts wherever they are shown.

The fuse a is inclosed in a tube 6 of refractory insulating material, such as porcelam, which is provided with caps or heads at d of metal cast or molded about its ends.

The terminals of the fuse mounting consist of screws 0 c, theheads of which are embedded in the molded heads or caps 11 d, the

' shanks of said screws projecting at the ends to receive binding nuts 0 e for securing the fuse-mounting to the usual supporting terminal clips (not shown). The extremities of the shanks of the screws 0 c are preferably enlarged by spinning, after the binding nuts are screwed. thereon, so as to prevent the removal of said nuts. These screws c c are electrically connected with the ends of the fuse wire a. Preferably the screws are of I the ordinary fiatheaded variety, and the heads of said screws, resting against the ends of the shell 1 offer their slots as channels through which the .ends of the fuse wire ma be bent and led from the bore of the shel into the-material of \the' caps, in which material they are embedded when said caps 1 are molded. The metal used for the heads or caps is preferably a lead allo The shell 1) is preferably. provided, wit off sets to interfock With' .the. 1oapa and revent "said caps from coming off. As 5 own, these offsets are recesses f f in the sides of the shell, near its'ends, so that the metal of the caps, when the latter are molded, will enter said recesses.

Porcelaintubes, such as ordinarily used for fuse-tubes, are irregular in form and are not adapted to make. a close, true fit with the-ordinary machine-turned caps, so that the joint is often loose. By my invention, the cap being cast or molded about the shell, conforms exactly thereto, and makes a tight fit. The use of an ordinary fiat-headed screw for a terminal, as above described, is also a very advantageous feature, as i 5 makes a very cheap construction, while pro viding an efficient manner of dis ends of the fuse wire and electrlcally connecting the. same to the terminals.

1. A fuse-mounting comprising body of soft 'metal molded about the end of the tube, a,'terhii.n.al.sc1'ew embedded and held in said body of soft metal, and. projecta tube, a

osing the ing therefrom, in combination with a fuse having a screw embeddedtherein, with the shank of said screw projecting through said head to receive a binding nut, in combination with a fuse Wire contained within said. tube and having its end embedded in the material of said molded head and thus electrically connected to said screw.

3. The combination with a tube, of a cap molded about the end of said tube, and a fuse wirepassing through said tubeand having its end embedded in the material of said cap.

' 4. The combination with a tube, .of a cap of soft metal molded about the end of said tube, a machine screwembedded in said metal cap, the shank of said'screwprojecting through said cap and the head thereof abutting against the end of said tube, and a fuse wire in the tube having its end led out through the channel offered by the slot in said screw, and embedded in saidmolded "metal cap.

5. The combination with a tuhegof. a body of soft metal, molded at the end of said tube, and a fuse wire passing through said tube and'having its end embedded in said body 0 soft metal.

6. A fuse mounting comprising a tube. at In witness whereof, I, hereunto subscribe body of soft metal molded at the end of said my name this 2nd day of April, A. D., 1907. tube, a terminal screw embedded and held JOHN T LYN'G in said body of soft metal and projecting L i, therefrom, in combination With a fuse Wire Witnesses:

in said tube having its end embedded in said W. THOMAS BOOTH, body of soft metal. FRANCIS X. MCGOWAN.
